#yocto howto use deltask

Hi,

my image build fails with:
ERROR: ims-image-fieldgate-1.0-r0 do_rootfs: The following packages could not be configured offline and rootfs is read-only: ['apparmor']

The image build succeeds if i remove the task pkg_postinst_ontarget_${PN} from apparmor_2.13.3.bb.

I tried to use deltask in my apparmor_2.13.3.bbappend with different settings:
deltask postinst_ontarget
deltask postinst
deltask pkg_postinst
deltask pkg_postinst_ontarget_
deltask pkg_postinst_ontarget_apparmor
deltask pkg_postinst_ontarget_apparmor_2

and

postinst_ontarget[noexec] = "1"
postinst[noexec] = "1"
pkg_postinst[noexec] = "1"
pkg_postinst_ontarget_[noexec] = "1"
pkg_postinst_ontarget_apparmor[noexec] = "1"
pkg_postinst_ontarget_apparmor_2[noexec] = "1"

but to no avail - I always get the rootfs error.

I know how to patch source files. But it seems there is no way to patch a recipe.
My workaround would be to make a copy of the apparmor recipe without the postinst part.

Is there a better or another way to do this?

Best regards

hu

You need to look into what the postinst_ontarget actually does, and why can
it only happen on target. Or do not use a readonly rootfs.

What about:

pkg_postinst_ontarget_${PN}() {
	:
}

in your bbappend? This should effectively override the task from a
bbappend (except if there are _append for the task).

Can't comment on this being a good solution to your problem but that
should work to remove the content of pkg_postinst_ontarget.

Hi Quentin,

thank you, the empty variant "removes" the task and the read-only-rootfs check works:
pkg_postinst_ontarget_${PN}() {
}

There are some issues which let me into the wrong direction. First I commented out the former code in the bbappend file. Apparmor builds, but the read-only-rootfs check fails:
pkg_postinst_ontarget_${PN} () {
#if [ ! -d /etc/apparmor.d/cache ] ; then
#    mkdir /etc/apparmor.d/cache
#fi
}

The same result you get with an empty line in the task:
pkg_postinst_ontarget_${PN}() {

}

For the following cases you get a parser errors:
pkg_postinst_ontarget_${PN}() {
 }
pkg_postinst_ontarget_${PN}() { }
pkg_postinst_ontarget_${PN}() {}

Thank you and best regards

hu
